From 645524a9c6e1e42dc4fe03217befb20e2fc4d43e Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 18 Dec 2008 23:12:16 +0100 Subject: mfd: Support configurable numbers of DCDCs and ISINKs on WM8350 Some WM8350 variants have fewer DCDCs and ISINKs. Identify these at probe and refuse to use the absent DCDCs when running on these chips.
